Patch Tuesday Analysis for January 2011

Just 2 Bulletins today both affecting workstations.

MS11-001 addresses a vulnerability in Windows Backup Manager only on Vista workstations.  It is publicly disclosed and proof-of-concepts have been made public.  To exploit this on the Internet, a user would have to be convinced that backing up on to the attacker's site is OK.  But you know losers - ahem - users!
 
MS11-002 is about 2 vulnerabilities with MDAC or WDAC (Data Access Components). We recommend giving first attention to this as it involves all supported versions of Windows and MDAC/WDAC. In the default Windows configuration with no third-party ODBC applications workstations are safe from the first vulnerability. For the second vulnerability as a workaround you can disable the ADO DLL but this will break MDAC.  
 
 
Ever wonder what the difference is between WSUS and enterprise, cross platform patch management systems like Lumension Patch and Remediation?  There's a big difference and you need the extra functionality more than ever as non MS vulnerabilities like those with Adobe products and Java overtake MS in terms of patch quantity and effort.  Check out this whitepaper: Lumension VMS vs Microsoft WSUS.

"I liked your high level overview of patches in the table. There are so many sources of patch information which can be very specific or surrounded by other stuff that it’s refreshing to get everything summarised like this. The “Randy’s Recommendation” comment is useful starting point too. Please keep up the good work."
